To all whom it may concern.-

Be it known that I, WILLIAM F. OLIN, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Grain-Harvesters, whichare fully set out in the following specification.

The purpose of this invention is to provide improved mechanism fortransferring the grain from the delivery end of the sidewise-deliveringplatform conveyer of a harvester to the binder. It comprises themechanism for ad- "ancing the grain sidewise from the platform conveyortoward the binder, the mechanism for moving the grain endwise andsimultaneously evening the butts, both before and after the sidewisemovement, and mechanism for adjusting the endwise-actuating mechanism,to adapt its action to the varying lengths of the grain, and therebyobviate the necessity for adjusting the binder back and forward for thatpurpose.

In the drawings, Figure 1. is a perspective, the'point of View being theinner rear corner of the platform. Fig. 2 is a perspective from aslightly-different angle, and having the rear and upper parts removed todisclose the interior mechanism. Fig. 3 is a plan, and 'Fig. 4 is a rearelevation, of the sidewise and the endwise actuating mechanisms. Fig. 5is a perspective detail ofa piece which forms a bearing for the sickle,and has also a bearing for the vertical shaft of the inner endwiseadjuster or butt-evener. Fig.6 is a perspective detail of a verticalcrank-shaft and its linkconnection for adjusting the outer endwiseactuating mechanism to long or short grain.

Fig. 7 is a similar detail of the sliding yoke, which is actuated by thecrank-shaft and carries'the endwiseadjusting mechanism. Fig. 8 is adetail ofa yoke and integral gear-wheel pertaining to the planetary gearsystem which act-uates the endwise-adjusting mechanisms. Fig. 9 is aperspective of the bracket-box B and the wheel B. Fig. 10 is a diagramto illustrate the action of the elevating and sidewise-actuatingmechanism.

A is the platform, comprising the endless conveyor A", a ribbed belt orapron of the usual construction, carried by the roller A", which isjournaled in the front and rear sills, A? and A, respectively. Uponthese sills is mounted the transverse conveyor and elevator B,hereinabove referred to as the mechanism for advancing the grainsidewise from the platform to the binder. Its construction is asfollows: Upon the sills A and A are secured the bracket-boxes B and Brespectively, the latter having rigid with it, concentric with itsjournal-bearing b the fixed gearwheel B. In these brackets is journaledthe shaft B, which receives motion from any convenient part of thedriving-train of the harvester or binder by chain over the sprocket--wheel B fixed near its forward end. It has rigid with it the disk Binside or just in the rear of the front bearing, and the disk B inside,in front of the fixed gear B on the rear bearing. Upon suitable studs onthe disk B are journaled three gear-wheels, 13*, arranged ina circleconcentric with the shaft B and equidistant from each other, and allmeshing with the fixed gear B. In a concentric circle outside that ofthe gear-wheels B are arranged six gear-wheels, B at equal intervals,and meshing two with each of the gears B, and each fixed to and carryinga shaft, 1), which shafts extend through to and are journaled in theforward disk, B Each of the shafts b is provided with teeth b, all oneach shaft being in the same axial plane, and constituting, with theshaft, a revolving rake, as seen in Fig. 2.

To the platfornrframe is secured the bracket-lip Bland to its upper edgeare secured the strips B bent over between the teeth I) in an arcinclosing the shafts If above and on the inner side, and extending downto a point about level with the axis of the roller A and thence curvedforward and upward, forming the trough b, and all secured to the stripB, a short distance from the end of the platform conveyer.

The binder-frame is supported on the main or platform frame, thesupports being concealed from view in the drawings -by the binder-deck.To the upper arm, O,of said binderframe are secured the brackets D, andto their outer ends is secured the bar D, to which are secured thebracket D and the brackets D D*. To the ends of the latter are pivotedthe lugs D fixed on the board D which is also provided with the stapleor loop D, under which is inserted the arm D of the bracket D, thusfurnishing the board D with three points of support from the bar D.Between the board D and the brackets D D are interposed the springs DD", for a purpose hereinafter stated. The board D overhangs thetransverse conveyer B, and is at a suflicient distance above it to allowthe unobstructed revolution of the teeth I) of the shafts E is the innerendwise adjuster. It comprises the vertical shaft E, stepped in thebearing 6, which is provided in the bracket 0, which is rigidly securedto the front sill, A. The shaft E has rigid with it the disk E at thebottom and the disk E near its upper end. Above the upper disk, D, theshaft is journaled in the bearing E of the yoke E. Said yoke has rigidwith it about the bearing F. the spur-wheel E. On the lower side of saidbearing and above said spur-wheel it has the annular boss E about saidbearing, and by means thereof it is itself j ournaled or pivoted in theend of the brace or horizontal bracket E. Said bracket E extends and issecured rigidly to the bar D at e and e and is braced and rendered morerigid by the brace E, as illustrated, but not necessarily. Said bracketis made in three pieces-viz., the arm E the extension E, at right angleswith the part E,and the corner-piece E, which is fastened at 36 to boththe other pieces, and affords the means of connection to the barD at e,as stated, bolted to it at e and to the bar D at 6"".

On the upper surface of the upper disk, E, are journaled, upon suitablestuds, two gearwheels, E E, meshing with the fixed spurwheel E atopposite sides thereof, and outside of each of said gear-wheels 15 andin diametrical line with each other are provided in said disk journalbearings for similar vertical shafts, 0 6 carrying at their upper endsthe gear-wheels 1G and journaled at their lower ends in the lower disk,.E. Said gear-wheels E E" mesh with and are driven by the gearwheels E Erespectively. To the shafts c e are secured the vertical vanes or bats ee, which are made rigid with the said shafts, re spectively.

F is the outer endwise adjuster, similar in the construction andactuation of its constituent parts to the inner adjuster, E. The lowerend of its shaft F is journaled in the journalboxf of the sliding yokef, which has the journal-box f 2 for the packer-shaft N,on which itslides and by which it is sustained. The shaft F has a shoulder torestupon the shoulderf of the journal-box f and sustain said shaft, andcarries on its lower end, within the yoke f, the bevel-gear F whichmeshes with and is driven by the bevel-gear F feathered and adapted toslide on the shaft N. At the upper end the shaft F is j ournaled in theyoke F, similar to the yoke E, and having above the rigid spur-wheel Fan annular boss precisely like the boss E on said similar yoke E whichconstitutes its bearing in the slot e of the extension E of bracket E".The yokes Etand have horizontal journalboxes LE and F, respectively, inwhich the horizontal shaft G is journaled. Said shaft has at its outerend the bevel-gear G, meshing with and driven by the bevel-gear F fixedon the upper end of the shaft F, and at its inner end the bevel-gear G,meshing with and driving the bevel-gear E fixed on the upper end of theshaft E. The gear-wheel G is feathered on the shaft G and adaptedthereby to slide on and revolve with it.

Upon any convenient fixed part of the frame in front of the transverseconveyor-as to the beam Xis fixed the vertical box H for the crank-shaftH, which is provided with the crank H, from which extends the link H tothe eye f of the sliding yokef. The crankshaft H is provided withsuitable stop, h,ab0ve the box H, and below said box has the coiledspring H stopped above by said box and below by the pin If, and tendingto hold thesaid shaft H, with its stop h,down against the box H. Rigidwith the shaft and with the crank H is the notched segment H, which isadapted to engage the tooth or stud h on the top of the box H and detainthe shaft H and the crank H and parts actuated thereby in any positionto which they may be brought by revolving said shaft H, as may be doneby means of the crank-handle H at its upper end.

The crank H stop h, and segment 11 are preferably made integral andafterward made rigid with the shaft by any convenientmeans, as theset-screw h".

To the sliding yokefis rigidly connected the rigid arm K, extendinghorizontally outward and forward to a point beyond the adjuster F, andbent upward at 7 and to its upright portion K is secured the butt-guardK".

The packers N are located in the usual position, and are actuated in thefamiliar manner by the cranks N, and strike up through the slots 0 c inthe binder-deck O. Said slots 0 c,and hence the vertical planes of thepackers, are both located rearward from the outer buttadjuster, as seenin Figs. 2 and 3.

I will now describe the operation of these devices.

First, the transverse conveyor B. The revolution of its shaft B,carrying the disks B and B, imparts to the gearwheels B a revolutionabout their own axes by reason of their engagement with the fixedspurwheel B, said revolution being in the same direction as that of thesaid disks. The gearwheels B impart to the gear-wheels B a revolutionabout their respective axes in the reverse direction to the disks. Thegear-wheels B are made equal in the number of their teeth to the fixedspur-wheel B and hence make one revolution on their axes to eachrevolution of the disks on their axis, the shaft B. Said revolution ofthe gear-wheels B"',being reverse in direction to that of the disks,causes their axial planes to remain unchanged in direction, and theirteeth I) on their shafts I) maintain an unvarying direction throughoutthe revolution of the disks. The said shafts IIO b have alternatelyvertical and horizontal teeth, three of them having their teethhorizontal and the alternating three having their teeth vertical. Thehorizontally-toothed rakes enter under the grain as itis delivered intothe trough b from the platform carrier and lift it, as they rise,withthe disks, through the inner quarter of the revolution, and as theybegin to withdraw within the circle of the strips B thevertically-toothed rakes begin to protrude their teeth and enter thegrain vertically from beneath, and carrying it over'the upper quarter ofthe revolution and down onto the binder-deck, which is preferably aboutmidway from the level of the shaft B to the top of the curve of thestrips B. At this point the packers seizethe grain; but with thesucceeding steps in the process this invention is not concerned. As thegrain is carried by the rakes over the top quarter of the transverseconveyer, it enters under the board D and is thereby restrained and keptwithin the control of the rakes. If the grain accumulates on the outerside of the transverse conveyer B during the intervals of binding, theboard B will be forced upward at its outer edge, turning on the pivotsin the lugs D and compressing the-springs D" D.

Second, the endwise adjusters. The power derived from the packer-shaft Ndrives first the outer, and from that, through the horizontal shaft G,the inner,endwise adjuster, Fand E, respectively. The arrangement of thegearing is similar in effect to that which actnates the transverseconveyer-rakes and gives to the vanes 6 and f an orbital motion aboutthe shafts E and F, respectively, and at the same time, by revolvingthem on their axes in the reverse direction, preserves their axialdirection without change. This direction is substantially parallel tothe vertical plane of the cut or at right angles to the axis of thetransverse conveyer. Their motion is therefore forward against the buttsof the grain and outward with its transverse or sidewise movement. Theinner adjuster, E, stands forward of the line of the sickle, and thehorizontal sweep of the vanes 6 extends close to the outer finger of thefinger-bar, so that they attack the grain at the heel of the sickle andprevent it from being obstructed at that point,.and thrust it backendwise a distancesufficient to prevent the butts overhanging theforward end of the transverse conveyer B and move stubbleward with itpast the sheath of the transverse conveyer and elevator B, as seen inFigs. 3 and 4.

movement, and thrusts it endwise such distance as may be necessary inorder that the band may encircle it at the proper point in the length ofthe grain. Since the distance-necessary to effect this result will varywith different lengths of grain, it is necessary to provide formovingthe outer adjuster back and forward at will without interrupting itsaction.- This is accomplished by the vertical crank- The outer endwiseadjuster, F, acts upon the grain by a precisely similarshaft H and itsconnections described with the sliding yokef. When the grain is short,said shaft, being revolved to the right, will slide the adjuster F toits extreme rear position, (illustrated in Fig. 4,) the yoke f slidingon the shaft N and causing the yoke F to slide in the slot 6 of theportion E of the bracket E the shaft G sliding through the gear-wheel Gthe yokes E F and f retaining the gears which they respectively embraceproperly in mesh through all variations of position. The butt-guard K,being secured to the yoke f, as described, moves with it, and in allpositions of the adjuster F corresponds accurately therewith;
